Vermont fire investigators are still trying to determine what caused a fire in a vacant Rutland home that killed two people.
At the same time, investigators say a second fire reported hours later in a separate vacant building in Rutland was deliberately set.
Police say they do not know if the two fires are related.
On Saturday afternoon, Rutland firefighters found two people dead in a vacant house after a fire. The city owns the building.
Early Sunday, firefighters were called to another fire on South Main Street in another unused structure that once housed a real estate building.
Police say they don't know the exact cause of the second fire, but it was believed to have been deliberately set.
